1 Ubuntu上部署ElasticSearch
准备一台服务器，IP是192.168.100.200
1.1 安装JDK8
首先需要部署JDK8+，这里我使用了JDK8
sudo apt-get install -y openjdk-8-jdk;
1.2 下载ElasticSearch
mkdir -p /home/user/softwares;
cd /home/user/softwares;
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.16.1-linux-x86_64.tar.gz;
1.3 解压，改文件夹名
tar -zxvf elasticsearch-8.16.1-linux-x86_64.tar.gz;
mv elasticsearch-8.16.1 elasticsearch;
1.4 修改参数，减少内存消耗量
vim /home/user/softwares/elasticsearch/config/jvm.options;
-Xms1g
-Xmx1g
vim /home/user/softwares/elasticsearch/config/elasticsearch.yml;
node.name: node-1 #配置当前es节点名称（默认是被注释的，并且默认有一个节点名）
cluster.name: my-application #默认是被注释的，并且默认有一个集群名
path.data: /home/user/elasticsearch/data # 数据目录位置
path.logs: /home/user/elasticsearch/logs # 日志目录位置
network.host: 0.0.0.0 #绑定的ip：默认只允许本机访问，修改为0.0.0.0后则可以远程访问cluster.initial_master_nodes: ["node-1", "node-2"] #默认是被注释的 设置master节点列表 用逗号分隔
xpack.security.enabled: false
xpack.security.http.ssl:
enabled: false
xpack.security.transport.ssl:
enabled: false
mkdir -p /home/user/elasticsearch/data;
mkdir -p /home/user/elasticsearch/logs;
1.5 启动
cd /home/user/softwares/elasticsearch/bin;
nohup ./elasticsearch &
1.6 宿主机访问
